TDA2040

25-watt hi-fi audio power amplifier

Datasheet − production data

Features

■ Wide-range supply voltage, up to 40 V

■ Single or split power supply

■ Short-circuit protection to ground

■ Thermal shutdown

■ P = 25 W @ THD = 0.5%, V = 1ꢀ V, R = 4 Ω

Pentawatt V

■ P = 30 W @ THD =10%, V = 1ꢀ V, R = 4 Ω

comprising an arrangement for automatically

limiting the dissipated power so as to keep the

operating point of the output transistors within

their safe operating range. A thermal shutdown

system is also included.

Description

The TDA2040 is a monolithic integrated circuit in

the Pentawatt package, intended for use as an

audio class-AB amplifier. Typically, it provides
